Opioid Dependence
Conditions
Brief summary
This study will compare the effects of brief strengths-based case management (SBCM) to the effects of screening, assessment and referral alone (SAR) in opioid-dependent patients. Participants meeting DSM-IV criteria for opioid dependence will be randomly assigned (150 per group) to receive 1) up to 6 sessions of SBCM; or 2) SAR. Follow-up assessments will be completed at 3 and 6 months, by staff who are blinded to treatment condition.
Detailed description
As addiction treatment becomes increasingly integrated into the medical care system, two models have rightly received a great deal of attention. The first is the use of Screening, Brief Intervention, and Referral to Treatment (SBIRT) models to identify cases, provide therapeutic contact, and refer the more severe cases to longer-term care. The second is the treatment of addictions using medical models of treatment, including those that can be implemented in primary care settings. Much less attention has been paid to optimizing strategies for bridging the gap between SBIRT and more intensive/longer-term treatment for those on the severe end of the spectrum. This factor is of critical importance for opioid dependent patients, whose needs are not met by brief interventions or brief treatment. Emergency room interventions for substance use disorders have been largely limited to brief interventions/SBIRT models, and these have focused primarily on alcohol. Although there is a substantial literature documenting the value of case management in linking drug users to treatment, this approach has not been applied to drug users in the emergency department (ED) setting. In a sample of opioid dependent patients seen in a medical ED who are not currently engaged in treatment, this study will compare the effects of brief strengths-based case management (SBCM) to the effects of screening, assessment and referral alone. Participants meeting DSM-IV criteria for opioid dependence will be randomly assigned (150 per group) to receive 1) Screening, Assessment and Referral or 2) up to 6 sessions of SBCM based on the model previously implemented by Rapp and colleagues in prior studies. Staff who are blinded to treatment condition will complete follow-up assessments at 3 and 6 months. Aims of the study are to identify the main effects of SBCM on substance abuse treatment initiation and engagement, use of opioids and other drugs, and broader measures of health and life functioning; to examine the interactions between treatment assignment and selected participant attributes in predicting treatment initiation, engagement, and substance use outcomes; and to examine effects of treatment involvement on substance use outcomes in the two treatment groups. The proposed study will be the first trial using a case management approach to link drug dependent patients presenting in EDs to longer-term addiction treatment. It will be one of the first trials focusing specifically on opioid dependent patients in medical EDs. A further innovative feature is that the case management approach will emphasize linkage to pharmacotherapy, facilitating linkage to office-based buprenorphine, methadone, or naltrexone for patients who desire this treatment.
Interventions
The six case management sessions for the proposed trial are based on those described in manuals developed by Dr. Rapp for two clinical trials, one supported by National Institute on Drug Abuse (NIDA) and another by the Centers for Disease Control (CDC). Each session is guided by specific objectives that promote linkage with and retention in substance abuse treatment, particularly pharmacotherapy for opioid dependence in a specialty or primary care setting. Objectives from the earlier trials will be adapted to fit the specific context of this trial, linking with and staying in treatment following an emergency department visit. Initiation of the relationship between client and case manager begins immediately following random assignment and termination takes place when either (1) six sessions have occurred; (2) ninety days have elapsed; or (3) clients discontinue involvement.
The research assistant will provide these participants with an information sheet listing treatment (including both specialty treatment centers and primary care clinics that provide buprenorphine) and self-help resources in their community. The referral sheet includes names, addresses, and phone numbers of local addiction treatment agencies. Because the emergency department does not currently screen or refer systematically, the SAR condition represents a level of care significantly higher than treatment as usual. Participants will also receive an informational pamphlet about drug use and its consequences, addiction, and treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Initiation of Treatment for Opioid Dependence | 3 months | Initiation is defined as a dichotomous outcome (yes/no), and is considered to have occurred if patients report any substance abuse counseling sessions (excluding SBCM) from the time of the baseline assessment up to the day before the three-month interview, as captured via self-report on the Form 90-D. |
| Engagement in Treatment for Opioid Dependence | 3 months | Using the same timeframe as initiation, engagement is defined as the number days of medication use for opioid dependence, based on Form 90-D self-report verified by clinic dosing logs and Prescription Drug Monitoring Program records. |

| Number of Participants With Successful Outcome for Opioid Use | 3 months | Successful outcome will be defined as 1) 3-month urine negative for opioids (opiates, oxycodone, methadone, buprenorphine, or propoxyphene) unless prescribed for opioid dependence, and 2) no more than two days of self-reported opioid use on the Form 90-D in the 4 weeks (30 days) prior to the 3-month evaluation. |
| Score on World Health Organization Quality of Life (WHOQoL) Brief Questionnaire | 3 months | The WHOQOL-BREF instrument comprises 26 items, which measure the following broad domains: physical health, psychological health, social relationships, and environment. Participants express how much they have experienced the items in the preceding 2 weeks on a 5-point Likert scale ranging from 1 (not at all) to 5 (completely). Domain scores are scaled in a positive direction (i.e. higher scores denote higher quality of life). Raw domain score is the sum of respective item scores. All domain scores are reported between 4 and 20. |
| Initiation in Participants With Higher Levels of Environmental Instability at Baseline | 3 months | Initiation is defined as a dichotomous outcome (yes/no), and is considered to have occurred if patients report any substance abuse counseling sessions (excluding SBCM) from the time of the baseline assessment up to the day before the three-month interview, as captured via self-report on the Form 90-D. |
